-cirIsEL HANDLE.

Application led September 1, 1925. SertalNo. 53,772.

To all whom t may concern Be it known that II, EDWARD J. WIQMER, a citizen of the United States, reslding at the city and county of Denver and State of Colorado, have .invented certain new and useful Improvements ,in CV isel Handles; and I dodeclare the following to be a full, clear, and exact description of the 1nvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being h'ad to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

, This invention'relates to improvements 1n chisel handles.

A carpenters chisel is'a tool that 1s oftentimes employed in such a way that the end of thehandle must be struck` by a hammer. As the handle is almost invariabl made from wood it readil splits and ecomes useless. To prevent t is splitting, it is customary to secure to the end of the handle one or more layers of leather, preferably sole leather. It has been' found from experience that leather willnot stand up under repeated hammerings, but willlose its resiliency andbecome iiabby. When this occurs the handle will split and become useless.

I have foundthat if I substitute for leather a material composed of highly compressed spinnable textile fibers that are held gether by means of a phenolic condensatlon product or synthetic rosin, such as bakelite,` that `better results are obtained than -wlth illustrated in its preferred forni4 and in which:

Fig. l shows a view of a carpenters chisel -provlded with my improved handle, a portion of the protective end member being Ain Fig. 1, and

broken away to show the manner of securinor the same .to the'handle;

ig. 2 is an end View of the handle shown Fig. 3 is a section takenon line 3 3 Fig. 1.

Numeralv 1 indicates an ordinary carpenters chisel having a socket 2 into which the handle 3 istted.` The outer-end of the handle has an axial cylindrical lug 4 which projects through an opening in the fibrous protector member 5. The function of the lug 4 is merely to hold the member 5 in place and it may therefore be ofcompara'- tively small diameter and should fit tightly in the opening of member 5. When a .hammer is employed for striking the end'of the handle, the force of the blow will be received by the end face of member 5 and transmitted evenly to the shoulder 6 of the handle 3.v Owing to the fact that member 5 is resilient and hard, it forms analmost perfect" protector for the handle. Member 5 is constructed of superposed layers of canvas which is first impregnated with a phenolic condensation product such as bakelite; the parts are then -highly compressed and subjected to suflicient heat to harden` the bakelite. Such an .article is Waterproof, resilient and tough and besides this it holds its fgrm and does not stretch or get out of s a I claim as new is:

1. A chisel handle having secured to one f end a protective member formed of Vhighly compressed fibrous material impregnated with a phenolic condensation product that has been hardened.

2. A chisel handle having secured to one end a protective member formed from a plu- .rality of layers of canvas that has been impre nated with a phenolic condensation pro uct-andcompressed.

31 A chisel handle having secured to 'its end a protector consisting of highly compressed canvas cemented together by means of a phenolic condensation roduct.

In testimony whereof I a my signature.

EDWARD J. WIDLER.
